GitLab Critical Security Release: 13.2.6, 13.1.8, 13.0.14


Note: due to a packaging problem, our previous release (published and
communicated earlier today/Aug 18) did not include the security fixes
mentioned in the accompanying blog post for the GitLab Community Edition
package. The new, just released versions of GitLab Enterprise Edition
and GitLab Community Edition now contain all the necessary fixes for all
versions. Please update all packages immediately. ***

Today we are releasing versions 13.2.6, 13.1.8, 13.0.14 for GitLab
Community Edition (CE) and Enterprise Edition (EE).

These versions contain important security fixes, and we strongly
recommend that all GitLab installations be upgraded to one of these
versions immediately.

GitLab releases patches for vulnerabilities in dedicated security
releases. There are two types of security releases: a monthly, scheduled
security release, released a week after the feature release (which
deploys on the 22nd of each month), and ad-hoc security releases for
critical vulnerabilities. You can see all of our regular and security
release blog posts here. In addition, the issues detailing each
vulnerability are made public on our issue tracker 30 days after the
release in which they were patched.

We are dedicated to ensuring all aspects of GitLab that are exposed to
customers or that host customer data are held to the highest security
standards. As part of maintaining good security hygiene, it is highly
recommended that all customers upgrade to the latest security release
for their supported version. You can read more best practices in
securing your GitLab instance in our blog post.


Deploy Token Access Control

An authorization issue discovered in the deploy token handling allowed
read access to public projects with restricted repositories. This issue
is now mitigated in the latest release and is waiting for a CVE ID to be
assigned.

Thanks @ledz1996 for responsibly reporting this vulnerability to us.


Versions Affected

Affects GitLab EE 10.7 and later.


Remediation

We strongly recommend that all installations running an affected version
above are upgraded to the latest version as soon as possible.
